It might seem kind of crazy that people would go to such lengths to get sperm from a specific place. Part of the reason is because in places all over the UK, there is a shortage of donor sperm.
As a result, Denmark has become the home to the world's largest sperm bank. The bank is called Cryos, and its slogan is "Congratulations, it's a Viking." You might be wondering why donor sperm is so sought after. A lot of it has to do with the way some women want to raise their kids.
Anonymous donors mean mothers won't have to worry about their children growing up wanting to find their fathers. On the other hand, people born from donor sperm can also sometimes identify any paternal half siblings they might have.
Still, the most pressing issue is the shortage of donor sperm in places like the UK. So many women travel abroad (out of the UK) because donors in the UK cannot be anonymous, so fewer men want to donate. Cryos allows donors to be anonymous and also pays them for donations.
